Be it known that I, THOMAS J."'IHoMrsoN, a citizen of the United States, residin at Climax, in the county of Polk and tate of Minnesota, have invented certain new and useful Improvements in Storm-Window Fasteners; and I do hereby declare the fol'- lowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to.whichit appertains to make and use the same.

fasteners; and, to this end, it consists of the novel devices 'and combinations of devices hereinafter described and defined 'in the claim.

"Inthe accompanying drawings, which illustrate the invention, like characters indiwindow sash removed from the window frame; and

operating lock studs.

The numeral 4 indicates a window frame having the customary inner, intermediate and outer sash stops 5, 6 and 7, respectively.

Upper and lower window sashes are hung between the stops 5, 6A and 7 for vertical sliding movement and are indicated, respectively, by the numerals 8 and 9. A storm window sash 10 is fitted in the window frame 4 and seated against the outer stp 7.

The numeral 11 indicates al pair of angle bars, which constitute the movable members of the improved fasteners. One .of the flanges 12 of these ,angle bars 11 rests fl t against the inner faces ofthe stiles of the storm window sash 10, and are connected thereto for limited endwise sliding movement by a plurality of longitudinally spaced slot and pin connections 13. The slots of these connections 13 are formed in the flanges 12, while the pins thereof are secured to and project laterally from the storm window sash 10. lThese pins are provided with heads, which prevent the angle bars- Specification of Letters Patent. j

't cate like parts throughout the several views. `2 0 l Figure 1 1s a vertical section taken cenfrom becoming detached.1 shown',are preferably in the form of round? lheaded screws. v The otherflanges of the angle bars 11 eX- tend at right angles from the Storm window sash 10 to aord lock blades 14, having formed therein oblique cam slotsll, open at their outer ends and arranged to engage and interlock with headed studs 16. These headed studs 16 are secured to and project from the outer stops 7 and, as shown, are preferably in the form of round-headed screws. The angle bars 11 extend substantially the full length of the stiles of the storm window sash 10, with just suliicient clearance between the top of the window frame 4 and the sill thereof to permit the required end- -wise movement of said angle bars. On the lower end portions of the angle bars 11, are hand holds 17.

By the use of the improved fasteners, it is possible to put on or take oli' a storm window sash from the inside of a building. To put on the storm sash v10, the lower sash 9 is first raised and the said storm sash inserted endwise through the window frame to the outside of 'the building and then raised and supported on vthe window-sill. While the storm window sash 10 is in this fposition, the same may be. held bythe hand holds 17 and, at the same time, the angle bars 11 moved to their uppermost positions to carry the flaring-open ends of the cam slots 15 into registration with the lock pins 16. Then by drawing inward and downward on the hand holds 17, the cam slots 15, acting on the pins 16, will draw the storm window sash 10 firmly against the sto 7 throughout its entire length. As there 1s a multiplicity -of, these cam slots 15 and cooperating -pins 16, the storm window sash 10 cannot spring awayy from the window stop 7, and if'the same is warped, at the time the same 1s put on, the lock blades 14l will draw the same .back into its original-`- `Ptentdlerl1913L Application led March 22, 1917.
